  • Publication number: 20200113511
    Abstract: The disclosure is directed to a system and methods for dynamic diagnosis of musculoskeletal conditions. The methods include monitoring at least one body part of a subject with at least one sensor, the at least one sensor configured to detect motions of the at least one body part of the subject, the at least one sensor comprising a Micro Electro Mechanical System (MEMS) sensor. The at least one sensor transmits kinematic data to a signature-comparing device. The methods include obtaining composite signatures of the subject based on the kinematic data, the composite signatures comprising at least one motion signature. The methods also include comparing the composite signatures of the subject to a normal composite signature to determine whether a difference between the composite signatures of the subject and the normal composite signatures is larger than a pre-determined threshold.

  • Patent number: 6699289
    Abstract: A glenoid component for securement to a glenoid surface of a scapula so as to provide a bearing surface for a head portion of a humerus includes a body having a first surface configured to contact the glenoid surface of the scapula and a second surface configured to receive the head portion of the humerus. The glenoid component also includes an interruption such as a buttress extending from the body. The interruption is configured to be received in a like-configured notch formed in the glenoid surface of the scapula. The interruption helps prevent movement of the glenoid component relative to the glenoid surface of the scapula after implant. The body also may include anchoring extending from the body for penetrating the glenoid surface of the scapula so as to help secure the body to the glenoid surface of the scapula. The glenoid component is used in one application to help correct bone defects and in another application for wear.
